Answer:

x=3.5

Step-by-step explanation:

The first step is to subtract both sides by 5 so you can find x alone

2x+5=12            (12-5=7)

2x=7        Now you divide both sides by 2 so that you have x alone and have the answer

x=3.5         (7÷2 = 3.5)

Answer:

x = 3 1/2

Step-by-step explanation:

subtarct 5 by 12 and 5

getting 2x = 7

now divide 2 by both sides
